I installed Visual Studio 2013 Professional as a Trial version while waiting for my company to complete the license purchase.

They completed the purchase of 4 licenses (64 bit), but were not given Product Keys. Instead, there is a particular .iso file with the license or product key embedded in some way.

I want to avoid having to uninstall Visual Studio 2013 only to reinstall Visual Studio 2013 and re-setup all my settings. Is this possible? Is there a way to extract the license/product key from the .iso or from other coworkers desktops that did a clean install?

Don't think there is a way to get the license key but if you just install the ISO it should just update your trial version and leave all your settings and other tools/installs intact. Should take less than hour.

@ScottWylie tried that, but didn't work because of new service packs. updated question to not repeat here

I'm voting to close this question as off-topic because it is not about programming as defined within the scope of the Help Center. This question should be addressed by Microsoft Support.

Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

Exit the registry

Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

Run the ISO (or vs_professional.exe) again. This time repair should be visible.

Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

it took 4 hours for repair to complete and solved nothing, however registering a product with newly created Microsoft account extended my licence for additional 74 days :)
